			   \item 1990 CAAA: Acid Rain program manted installing NOx monitoring and abatement normally met with control technology
			   \item In 1995 Ozone Transport Commission required existing sources to meet RACT limits and ran OTC NOx budget program

			   \item Bill establishing market included complementary programs and modifications of existing programs, including LCFS, RPS, and efficiency mandates 
			   \item LCFS adopted in 2009 and “require[d] the carbon intensity of transportation fuels to be reduced by at least ten percent in 2020” (ARB, 48). “In April 2011 California adopted a 33 percent RPS” (Appendix, 21). The efficiency mandates varied by different buildings and appliances (ARB, 37).

			   \item 1970 CAAA: NSPS, BACT
			   \item In 1990 South Coast Air Basin was only nonattainment area for NOx emissions. Thus, the NOx emissions standards may have been more stringent here than other areas.
			   \item Prior to RECLAIM, command-and-control program emphasized advanced control technologies, which they adopted in late 1989.
